Abstract: Aiming at the properties of large transversal change,strong heterogeneity and highly difficult exploration reservoirs of Jialingjiang formation in Southeast area of Sichuan,taking T1j1 for example,based on stratigraphic correlation,pore micro-geometry and physical properties,acoustic impedance inversion is carried on and its interpretation scheme combining reservoir geologic with geophysics response characteristics is determined,distribution of favorable reservoir is predicted.According to the reservoir geologic characteristics and optimized seismic attribute,step wise regression is used to establish the relationship between seismic attribute and reservoir porosity to predict distribution of reservoir porosity.Finally,the favorable exploration area is pointed out by the results of reservoir geologic inversion and porosity prediction.The method combining geology and geophysics gives the more reasonable geologic interpretation for reservoir prediction and porosity inversion,effective result is obtained.

Key words: Jialingjiang Formation, geologic characteristics, inversion, seismic attribute, Southeast area of Sichuan
